Abstract: To determine the reliability of concentric quadriceps muscle torque at 30°, 60 °, and 75 ° of knee extension, 25 female university students were studied. Each subject was tested on the Kin-Com isokinetic dynamometer on 2 separate days, 7 days apart. The dynamometer's speed was set at 60 7s. Intraclass correlation coefficients for 30°, 60°, and 75 ° were 0.84 (p
